Engineered for quick charging systems, refrigeration testing, and premium system hermeticity in industrial installations.
The industrial metropolitan area of Barcelona, encompassing zones like Zona Franca and Vallès, represents one of Southern Europe’s key manufacturing and logistical hubs. As Catalonia accelerates its transition toward eco-efficient technologies, strict regional adherence to the updated European Union F-Gas Regulation (EU) 2024/573 demands absolute hermeticity in HVAC/R networks. Fast, zero-leakage maintenance loops are no longer optional—they are a compliance standard.
In this strict climate, our precision-manufactured R134a adapters and high-reliability brass quick couplers serve as the first line of defense during system commissioning, refrigerant recovery, and assembly line charging. Standard fittings fail under the mechanical stresses of rapid manufacturing loops; our designs leverage high-purity brass alloys and double vulcanized internal seals to prevent volatile organic compounds (VOCs) and halogenated gas leakages.
Combining 35+ years of R&D expertise with automated manufacturing to deliver unparalleled price-to-performance metrics.
Founded in 1988 as the Xiangshan Refrigeration Accessories Factory of Zhejiang University. Our design foundation rests upon academic and thermodynamic research, ensuring optimized fluid dynamics in every coupling element.
Equipped with core German CNC machining cells and Japanese testing systems. We execute automated helium mass spectrometer leak detection and thermal shock validation from -35°C to 75°C for 500+ hours.
Operating under strict ISO 9001:2015 registration. Our products carry UL validation and full compliance with RoHS and REACH standards, guaranteeing seamless customs clearance and safety inside the EU market.
Every batch of quick couplers, service valves, and copper filter driers undergoes a standardized validation sequence to assure operational durability in demanding maritime transport and production line environments:
From a university laboratory offshoot to a prominent manufacturer of HVAC/R critical accessories.
Established as the Xiangshan Refrigeration Accessories Factory of Zhejiang University, focusing on high-quality filtration designs.
Construction of our primary dedicated production facility, scaling copper component production capacity to support global exports.
Implementation of the MES intelligent workshop management system, securing real-time quality logging and production trace loops.
Adapting manufacturing lines to produce zero-leak quick couplers and components optimized for low-GWP natural refrigerants (R290, R600a).
Ensuring high-end durability for engineers and purchasing managers in Barcelona and beyond.
Our couplings and filter driers are designed with heavy-duty operational contexts in mind. In coastal cities like Barcelona, saline moisture accelerates standard metal oxidation. We mitigate this through controlled alloy compositions and protective surface treatments.
